Evri witnessed a 30% rise in US parcel deliveries over the last week, Retail Week reported, as various global postal services have confirmed they will be pausing deliveries amid tariff uncertainty.

It comes as the de minimis exemption, which allowed packages worth under £593 ($800) to be free from relevant duties, ended today (29 August). This means lower value parcels will now face tariffs implemented by the US government depending on their country of origin.

Some carriers have said they will pause parcel deliveries to the US.

All products delivered via the postal network need to apply for either the effective country-specific tariff rate or a fixed fee dependant on the tariff rate of their country of origin, according to the executive order which suspended de minimis on 30 July.

This will put a notable administrative burden on the US Postal Service, leading to potential disruptions.

However, express courier companies including Evri, UPS and FedEx are able to deliver outside of the postal network, so do not necessarily face the same disruption levels. Shipments will face a broader range of fees.

Evri explained set up a new service in May before the de minimis deadline in a bid to avoid disruptions.

Retailers can either utilise a model where the courier manages and charges back taxes and duties to the retail business or one where the shopper needs to cover the bill.

Evri director of international Craig Lee said: “We’ve trumped the tariffs and are pleased to offer a solution to remove the risk for those businesses, by doing the leg work and collecting parcel taxes and duties up front, supporting UK-based SMEs to retain a crucial income stream in a challenging retail climate.”

Earlier this month, Amazon warned that it might not hit market expectations on its operating income, over fears President Trump’s tariffs would impact its ecommerce operations.

JD Sports also cautioned that the year ahead would be challenging in April due to market volatility and tariff uncertainty, despite meeting its full-year profit expectations.

Correction: An earlier version of this article said Royal Mail had said it will pause parcel deliveries to the US. This is not the case.
